Specification of Letters Patent No. 33,127, dated August'', 1861.

To all 'whom it may concern:

e it known that I, firmati F. Bnnorrnn, of Chicago, in the county ot @ook and State oi Illinois, have invented a new and usetul Improvement in Stoves; and I do hereby declarethat the following is ay Jfull, clear, and exact description of the saine, reference being had to the annexed drawings, making a part of this sgecii'ication, in which- Figure l, is a vertical central section of my invention taken in the line a, m, Fig. 2. Fig. 2, a horizontal section of ditto, taken in the line y, y, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to an improvement in that class ot stoves in which an air-heating and radiating stove are combined; or, in other words, those stoves which are provided with an air-heating chamber or passage in close Contact with the iii-e chamber and soV arranged as to take cold air from the lower part of the room and discharge heated air trom its upper part.

' The invention consists in having an in-` verted conical air-heating chamber placed within the stove and extending from the lower to the upper part of the latter, the lower end of the airheating chamber being` curved and projecting through the side of the stove and the upper end secured to the top of the stove and closing the upper end of the saine, whereby it is believed that a more eiiicient conibination than usual of an air-heating and radiating stove is obtained.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents the body of a stove which may be of cylindrical or other form. I3, is the tire-chamber, C, the base which contains the ash-drawer I), and E, the smoke pipe or fiue. These parts may be constructed in the usual way and therefore do not require a minute description.

F is an inverted conical chamber or airheating chamber which is fitted within the body A, of the stove and extends from just above the tire-chamber B, to the top of the body A. The lower part a, of the chamber F is curved and extends through the side of boov A to communicate with the external air and tue upper end oi: said chamber Just iilisthe top ot the body A, and closes it.

rilie upper end of the chamber F, is provided Y with a perforated cap G, as shown in Fig. 1.

ihe air-heating chamber F, may be oi' cast-iron, the body A, of sheet-iron, and the {irenchainber B, oif cast-iron or sheet-iron with a lire-brick filling. y

I'Vhen a fire is `kindled in the stove, the chamber F, will be heated and a draft or current oiu air will pass through the chainber F, and be heated in said chamber and discharged in a heated state from the upper end ot' chamber F. The conical form of F insures a good draft or current of air .through it, and also owing toits capacity been placed at the upper part of the body A,

and have proved to be quite inefficient and comparatively expensive. My improvement it will be seen may be applied at a small cost not materially augmenting the cost of an ordinary cylinder or other radiating stove. Another advantage of my improvement is that the conical forni of the air chamber allows the fire to strike directly, or shine upon the surface of the air chamber, from top to bottom, thus exposing a ltar greater area of surface to the act-ion of the Aire, than would be the case if the sides of the air chamber were perpendicular-which is the common construction. I also obtain a :turther advantage by having the lower end or bottom of the air chamber curved, or made in arched form. rIhis forni presents the greatest amount of strength at that part where the most strength is needed; viz., the parts nearest the fire. In other stoves the bottom of the air box is generally horizontal, being made of a disk. Such bottoms are liable to crack and drop out, by exposure to great heat.

I d0 not claim broadly the employment or use of an air-heating chamber in a radiating stove for that has been previously applied to stoves and arranged in vVarious Ways; but,

I do claim as new and desire to secure by Letters Patent:

The arrangement of the urved conical air chamber F, with the stove body A, and fire chamber B, n the manner herein shown and Y WM. F. BEECHER.
